The official Python library for the Picket API

Installation

pip install -U picketapi

Usage - Quick Start

Use the Picket class to create the Picket API client. It takes a secret API key as a parameter.

from picketapi import Picket

picket = new Picket("YOU_SECRET_API_KEY")

Nonce

A nonce is random value generated by the Picket API to that user must sign to prove ownership a wallet address. The nonce function can be used to implement your own wallet authentication flow.

A nonce is unique to a project and wallet address. If a nonce doesn't exist for the project and wallet address, Picket will generate a new nonce; otherwise, Picket will return the existing nonce. A nonce is valid for two minutes before self-destructing.

resp = picket.nonce(chain="solana", wallet_address="wAlLetTAdDress")
# resp is of type NonceResponse
print(resp.nonce)

Auth

auth is the server-side equivalent of login. auth should only be used in a trusted server environment. The most common use-case for auth is linking a wallet to an existing application account.

resp = picket.auth(chain="ethereum", wallet_address="0x1234567890", signature="abcdefghijklmnop")
# resp is of type AuthResponse
print(resp.user)
print(resp.access_token)

Authz (Authorize)

authz stands for authorization. Unlike Auth, which handles both authentication and authorization, Authz only handles authorization. Given an authenticated user's access token and authorization requirements, authz will issue a new access token on success (user is authorized) or, on failure, it will return a 4xx HTTP error code.

resp = picket.authz(access_token="xxx.yyy.zzz", requirements={ "contractAddress": "0xContract" })
# resp is of type AuthResponse
print(resp.user)
print(resp.access_token)

Validate

validate validates an access token. validate should be called, or manually access token validation should be done, server-side before trusting a request's access token. It's common to move access token validation and decoding logic to a shared middleware across API endpoints. If the access token is valid, validate returns the decoded claims of the access token.

resp, err := picket.validate(access_token="xxx.yyy.zzz", requirements={"contractAddress": "0xContract", "minTokenBalance": "100"})
# Response is the decoded access token (AuthorizedUser)
print(resp)

Verify Token Ownership

If you only want to verify token ownership server side for a given wallet, tokenOwnership allows you to do just that.

resp = picket.token_ownership(
			chain="solana", 
			wallet_address="waLLETaddRess", 
			requirements={  
			  "collection": "METAPLEX_COLLECTION",
			  "minTokenBalance": "3",
			}
		)
# Response is of type TokenOwnershipResponse
print(resp.allowed)
print(resp.tokenBalances)
